ROLLER-BEARING CAGE.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed September 23, 1917. Serial no. 193,717.

'1 '0 all 11:72am it may concern Be it known that I, JEREMIAH BINGHAM, a citizen of the United States of America, residing at Toledo, in the'county of Lucas and State of Ohio, have invented certain new and useful Improvements in Roller Bearing Cages, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to roller bearings of that type in which the rolls are first housed in individual cells and subsequently assembled in predetermined relation to each other. The present invention has particular reference to the construction of a cage formed of an assembled series of rolls and the means for imparting strength and rigidity thereto, as hereinafter set forth.

In the drawings: Figure 1 is a sectional plan view of acage formed of a series of housed rolls;

Fig. 2 is a cross-section therethrough;

Fig. 3 is a detail view showing the alining members holding the rolls;

. Fig. 4 is a view of one of the roll cells or housings.

The individual 'cells or roll housings which.

are assembled to form the cage are preferably formed from pressed sheet-metal, comprising opposite segmental ortions A and connected by end portions and D. These end portions C and D outwardl -extending flanges E and F, with tongues r and H projecting centrally from the flanges. I and J are connector rings, preferably formed of pressed sheet-metal, and which are provided with grooves K and L for receiving the flanges E and F of the individual cells and are also provided with slits or apertures M for receiving the tongues G and H The apertures M are suitably spaced around the connector rings to produce the desired arrangement of the rolls.

here, as shown, the rolls are conical the rings I and J are of different diameters suitable to produce the proper alinement of the axes of the rolls in a common point of intersection. The larger ring I is preferably formed with an obliquely-extendlng' flange N which forms an abutment or bearing for the upper ends C of. the roll housings, and the oblique arrangement also braces and stifi'ens the ring. Thus when the tongues G and H are passed through the apertures M and bent over the flanges E and F will be reare provided with therein, connector rings tained in thegrooves K and L; also the ends and central portions of these flanges will bear upon opposite sides of the grooves, thereby forming a three-point bearing, as ndicated at O 0 0 which will hold the lndividual cells or housings from turning. The tongues G when bent over preferably engage recesses or depressions P in the bead Q, whlch latter is formed by the pressing of the groove K in the blank, and this construction avoids any projection or roughness incldent to the turning over of the tongues. t also provides greater clearance at the large end of the bearing which is sometimes essential to its use.

In assembling the cage, the roll cells or housings having the rolls therein are engaged with rings of suitable dimension, and it is obvious that the same housed roll units may be assembled in varying numbers with rings of difi'erent sizes. threaded through the slits in the rings they art bent'over and secured by suitable closing dies. During the closing operation the rolls are held in true alinement, preferably as shown in Fig. 3, by being engaged with outer and inner bearing rings R and S and radial alining members T. Thus when pressure is brought to bear by the closing dies the cells will be "secured in exactl predetermined positions, such as to hold all of the rolls with their axes intersecting a common point. Moreover the structure is a rigid one which will maintain the rolls in alinement when ifi service.

The cage constructed as described has a minimum of Weight and maximum of strength and rigidity, and at the same time it can be manufactured at low cost and in various sizes, employing the same housed roll units.

What I claim as my invention is:

1. A roll-holding ca e, comprisin a series of individual roll-hol ing cells or having rolls therein, connector rings at opposite ends of said cells, one of said rings being strengthened, and means for attaching the cells to. said rings for holding the same in exactly predetermined alinement and anchored a ainst rotative adjustment.

2. A roll-holfiug ca e, comprising a series of individualroll-holding cells or housings of tapering form and having conical rolls for the opposite ends ousings of said cells, the ring at After the tongues are.

the large end of the of tapering form and having conical rolls 4 cells being provided with an oblique-flange. forming a bearing for the endof each cell, and tongues on said cells projecting through apertures in said'ring and clenched to retain the same.

3. A roll-holding cage, comprisin a series of individual roll-holding cells or ousings therein, grooved connector rings at opposite ends of said housings, flanges projecting from the ends of said cells engaging said grooves with bearings on opposite sides thereof to .form a non-rotative engagement, tongues projecting from said cells passing through and an oblique flange on the ring at the large end of said cells forming a bearing for the ends thereof and also trussing the ring to impart rigidity'thereto.

4. A roll-holding ca e, comprising a series of individual roll-hol ing cells or housings,

a grooved connector ring at the ends of said I spaced depressions in said bead apertures in said rings and clenched, i

housings, flanges projecting from said housings engaging the groove in said ring, having a two-point'bearing on the outer face and an lntermediate bearing on the inner face thereof, and a tongue on each cell or f JEREMIAH BINGHAM.
